This code is part of the GNU C - Library, but also included in many other GNU distributions. Compiling - and linking in this code is a waste when using the GNU C library - (especially if it is a shared library). Rather than having every GNU - program understand `configure --with-gnu-libc' and omit the object files, - it is simpler to just do this in the source for each such file. */ - -#define GLOB_INTERFACE_VERSION 1 -#if !defined _LIBC && defined __GNU_LIBRARY__ && __GNU_LIBRARY__ > 1 -# include <gnu-versions.h> -# if _GNU_GLOB_INTERFACE_VERSION == GLOB_INTERFACE_VERSION -# define ELIDE_CODE -# endif -#endif - -#ifndef ELIDE_CODE #if !defined _LIBC || !defined GLOB_ONLY_P - -#if defined STDC_HEADERS || defined __GNU_LIBRARY__ -# include <stddef.h> -#endif - #if defined HAVE_UNISTD_H || defined _LIBC # include <unistd.h> # ifndef POSIX @@ -73,22 +43,13 @@ # endif #endif -#if !defined _AMIGA && !defined VMS && !defined WINDOWS32 -# include <pwd.h> -#endif +#include <pwd.h> -#if !defined __GNU_LIBRARY__ && !defined STDC_HEADERS -extern int errno; -#endif +#include <errno.h> #ifndef __set_errno # define __set_errno(val) errno = (val) #endif -#ifndef NULL -# define NULL 0 -#endif - - #if defined HAVE_DIRENT_H || defined __GNU_LIBRARY__ # include <dirent.h> # define NAMLEN(dirent) strlen((dirent)->d_name) @@ -117,17 +78,28 @@ extern int errno; #endif /* When used in the GNU libc the symbol _DIRENT_HAVE_D_TYPE is available - if the `d_type' member for `struct dirent' is available. */ -#ifdef _DIRENT_HAVE_D_TYPE -# define HAVE_D_TYPE 1 -#endif - -#if _LIBC -# define HAVE_DIRENT64 1 -#endif + if the `d_type' member for `struct dirent' is available. + HAVE_STRUCT_DIRENT_D_TYPE plays the same role in GNULIB. */ +#if defined _DIRENT_HAVE_D_TYPE || defined HAVE_STRUCT_DIRENT_D_TYPE +/* True if the directory entry D must be of type T. */ +# define DIRENT_MUST_BE(d, t) ((d)->d_type == (t)) + +/* True if the directory entry D might be a symbolic link. */ +# define DIRENT_MIGHT_BE_SYMLINK(d) \ + ((d)->d_type == DT_UNKNOWN || (d)->d_type == DT_LNK) + +/* True if the directory entry D might be a directory. */ +# define DIRENT_MIGHT_BE_DIR(d) \ + ((d)->d_type == DT_DIR || DIRENT_MIGHT_BE_SYMLINK (d)) + +#else /* !HAVE_D_TYPE */ +# define DIRENT_MUST_BE(d, t) false +# define DIRENT_MIGHT_BE_SYMLINK(d) true +# define DIRENT_MIGHT_BE_DIR(d) true +#endif /* HAVE_D_TYPE */ /* If the system has the `struct dirent64' type we use it internally. */ -#if defined HAVE_DIRENT64 && !defined COMPILE_GLOB64 +#if defined _LIBC && !defined COMPILE_GLOB64 # if defined HAVE_DIRENT_H || defined __GNU_LIBRARY__ # define CONVERT_D_NAMLEN(d64, d32) # else @@ -142,7 +114,7 @@ extern int errno; (d64)->d_ino = (d32)->d_ino; # endif -# ifdef HAVE_D_TYPE +# ifdef _DIRENT_HAVE_D_TYPE # define CONVERT_D_TYPE(d64, d32) \ (d64)->d_type = (d32)->d_type; # else @@ -165,126 +137,18 @@ extern int errno; # define REAL_DIR_ENTRY(dp) (dp->d_ino != 0) #endif /* POSIX */ -#if defined STDC_HEADERS || defined __GNU_LIBRARY__ -# include <stdlib.h> -# include <string.h> -# define ANSI_STRING -#else /* No standard headers. */ - -extern char *getenv (); - -# ifdef HAVE_STRING_H -# include <string.h> -# define ANSI_STRING -# else -# include <strings.h> -# endif -# ifdef HAVE_MEMORY_H -# include <memory.h> -# endif - -extern char *malloc (), *realloc (); -extern void free (); - -extern void qsort (); -extern void abort (), exit (); - -#endif /* Standard headers. */ +#include <stdlib.h> +#include <string.h> /* NAME_MAX is usually defined in <dirent.h> or <limits.h>. */ -#if defined HAVE_LIMITS_H || defined __GNU_LIBRARY__ -# include <limits.h> -#endif +#include <limits.h> #ifndef NAME_MAX # define NAME_MAX (sizeof (((struct dirent *) 0)->d_name)) #endif -#ifndef ANSI_STRING - -# ifndef bzero -extern void bzero (); -# endif -# ifndef bcopy -extern void bcopy (); -# endif - -# define memcpy(d, s, n) bcopy ((s), (d), (n)) -# define strrchr rindex -/* memset is only used for zero here, but let's be paranoid. */ -# define memset(s, better_be_zero, n) \ - ((void) ((better_be_zero) == 0 ?
